GREEN BAY, Wis.—Ryan Grant should wind up getting the majority of the snaps Sunday with James Starks still hobbled by an ankle injury.

Grant is coming off his best game in two years and looked revived. He was setting up blocks and then using cutbacks into large holes. It was the best the offensive line has run blocked in a while and Grant took advantage of of it.

In addition to Starks, there's a chance rookie Brandon Saine (concussion) won't play, either. That would leave Grant and John Kuhn to handle all of the halfback duties.

If either one of those two got hurt, the coaches would use one of the four tight ends as the fullback. As it is, the fullbacks will see some duty at running back.

The Chiefs rank 26th in run defense, but the offense hasn't run particularly well on the road.

Notes: Aaron Rodgers promises to keep spreading around the ball even though his trusty companion, WR Greg Jennings (knee), won't be available. It would be logical to think that Rodgers might hone in more on TE Jermichael Finley or WR Jordy Nelson, two of his big-play targets, but he has distributed the ball well this year and there's no reason to believe WRs James Jones, Donald Driver or Randall Cobb won't get attention from Rodgers. The offense won't change much with Jennings out, but the matchups will. Rodgers will throw to the guy who he thinks is winning his matchup. ...

G Josh Sitton practiced in team drills Thursday and has a shot to play Sunday. If he is cleared, it's likely he would either rotate with Evan Dietrich-Smith or go in for one chunk of time and then be done. The coaches want to get Sitton up and running before the playoffs begin because he's such an important part of the pass-blocking unit.
